Given:
Initial velocity = u= 50m/s
g=10m/s²
1) maximum height = h= u²/2g
=50x 50/2x10
=125m
2) time taken to reach maximum height(time of ascent)=t1=u/g⇒50/10
=5sec
Initial velocity = u= 50m/s
g=10m/s²
1) maximum height = h= u²/2g
=50x 50/2x10
=125m
2) time taken to reach maximum height(time of ascent)=t1=u/g⇒50/10
=5sec

✬ Maximum Height = 125 m ✬
✬ Time Taken = 5 Seconds ✬
Explanation:
Given:
- Initial Velocity u = 50m/s
- Final Velocity v = 0 ( at Maximum height )
- G = –10 m/s² ( going upward )
To Find:
- How hight would the particle rise and what time would take to reach highest point?
Solution: We know that :-
★ 2gS = v² – u² ★
• Putting all the values in given formula •
2 x –10 x S = 0² – 50²
–20S = – 2500
S = –2500/–20
S = 125 m
Hence, The Maximum height reached by the stone will be 125 m.
→ To find time we will use the formula
★ V = u + gt ★
0 = 50 + (–10) x t
0 = 50 –10t
–50 = –10t
–50/–10 = t
5 = t
Hence, The time taken by the particle to reach the maximum height will be 5 Seconds.
